Answer:
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a direct variation if it can be expressed in the form or
In a direct variation the constant of proportionality k is equal to the slope of the line m and the line passes through the origin
therefore
in this problem
-----> represent a direct variation
When two variable quantities have a constant (unchanged) ratio, their relationship is called a direct variation. It is said that one variable "varies<span> directly" as the other...simply when the y-intercept is zero. So the best answer is f(x)=2x</span>

Answer:
n= -9
Step-by-step explanation:
-3 ( n+5 ) = 12
-3n - 15 = 12
-3n = 12+15
-3n = 27
n = -27/3
n = -9
5/12*6 =5/12*6/1 crosscancle you get 5/2 the you get 2 1/2
